Problem

The temperature dependence of the standard Gibbs free energy change for a reaction is described by

\Delta G^\circ\, (\text{kJ}) = 32.4 - 0.092\,T,

where

T

is in kelvins. (i) Determine the standard enthalpy change

\Delta H^\circ

for the reaction. (ii) Determine the standard entropy change

\Delta S^\circ

for the reaction. Report

\Delta S^\circ

\text{J mol}^{-1}\,\text{K}^{-1}
